To all whom it may concern:

Be it known that I, LUCIFER J. MOST, a citizen of the United States,residing at New York, in the county and State of New York, have inventedcertain new and useful Improvements inMagazine Pencils; and I doherebydeclare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make anduse the same.

This invention relates to improvements in magazine pencils and hasparticular reference to the general type of pencil embodied in mycopendin application, filed August 22, 1918, Serial To'. 251,457.

The objects of the invention are to provide a pencil as described whichwill embody in its construction, a simple means whereby perfectalinement or register of the parts is' assured when they are securedtogether after filling and refilling; and to provide means wherebythe'supply leads may be thrust simultaneously from the magazine to apoint suficientlyremoved from the writing end of the casing to permitthe leads to be easily grasped and inserted in proper relation to thelead-projecting mechanism. I

These objects are accomplished in the device disclosed in theaccompanying drawings, inl which similar reference numerals designatesimilar parts and in 'which- Figure 1 is a view showing the pencil inuse.

Figure 2 is a longitudinal section slightly enlarged, through thepencil;

Figure 3 is a detail View of a part which will hereinafter be termed thefeeder;

Figure 4 is an enlarged perspective view of some of thepartsdisassembled, and

Figure 5 is a fragmentary elevation of the lower extremity of the pencilillustrating the manner ofprojecting the leads.

Referring in detail, to the parts, 1 designates an outer casing. 2 is acorrugated magazine barrel which is secured concentrically within thecasing and embraces a hellcally grooved tube or feed operating member 3.The member 3 is securedto a tube 4 forming a part of a cap 5 held uponone end of the casing 1, in such manner as to be capable of rotationthereon. A 'guide and lead-containing cylinder 6 is held within the tube3 which tube extends approximately serial No. 488,006.

the length of the shell and is provided with a longitudinal slot 7 and alug 8 acting to retain the cylinder 6 in its proper position.

lVithin the lead-containing cylinder is a feeder or propelling bar 9having a uniform thickness throughout its'length and formed with a pairof offsets 10 which function in alternate grooves of the tube 3 andengage through and along the slot 7 in the lead-containing cylinder.

An inner nozzle 11, tapered at its-outer extremity and formed with athreaded p0rtion 12 at its inner proximal end, engages over and isattached to the outer end of the lead-containing cylinder. This innernozzle has soldered thereto a multi-sided extension 13, which virtuallyconstitutes the distal end of the nozzle, and each side of which snuglyengages the corresponding innermost wall of each corrugation of thebarrel with the angle between anytwo adjacent sides of the extensiondisposed intermediate the outermost wall of each corrugation. Provisionis thus made for connecting the nozzle 11 with the barrel in anextremely rigid manner, andhaving established such rigidity, aperfectfit between the inner terminal of outer nozzle 14 and the adjacentterminal of casing l, as at 11. Outer nozzle 14, tapered at one end andinternally threaded at the other, engages the threaded portion of theinner nozzle and acts as a closing member for the magazine section.

The magazine is defined by the inner wall of the shell and the outerWalls of the corrugations of the barrel. In each corrugation, a lead 15is held in reserve, while the active lead is maintained axially of thecylinder 6 and the nozzle 11. As the lead is consumed, the point is fedoutwardly by turning the cap 5 and the operating member 3, the groovesof which, upon engaging the offsets 10, will constrain the feederoutwardly and thus force the lead out of the holder. It is obvious thatan opposite turning movement of the cap will draw rthe feederI inwardly.

As explained at length in my .copending application, when it is desiredto insert a new lead, the outer nozzle 14 is 'removed and the end of theinner nozzle is tapped' against the hand or other object. In thisposition, as exhibited in Fig.` 5, all of the leads in the magazine willpartially gravithe magazine.

writing. The important point to bear in mind is that no matter liovv`fragile the leads "may be, they are preserved `intact because the rendof the nozzle receives and absorbs the impact, the nozzle strikes theobject first,

and-the leads folloiv. Furthermore,` the screwtliieaded'base 12 of thenozzle serves as an extended bearing for the leads; that is, j

a bearing in addition to the oneaioided by Thisv is important'too, for

i when the leads have been projected as illusgersl are placed in aposition to grasp one trated in Fig. 5,*aiid the tips ofthe finof the`leads, the space `is so limited that a slight fiexing of theitmvoadjacent leads is boi'iiid to ensue, and iveie it not for the rvpresence'of this extendedbearing,"the leads ylivoiild be broken quitefrequently. i

Having thus described this inventiomll claim:

2, A pencil having a casing provided with portion thereof smaller thanth-e interior pe-, riphery of said-reservoir, means on said nozzleforming acontinuation of' the interior Wall of said' reservoir wherebyleads When slid from the` reservoir Will be thereby spaced from thesmall portion of the nozzle to yfacilitate their being grasped by thefin-` gers, and a closure member for said resern voir.
